I believe that in CGI mode, you can only have one output projection, so your approach won't work.
You can support multiple SRS/projection in WMS mode. To do this, you put multiple SRS codes in the wms_srs metadata for a layer. You might be able to change the map projection on the fly by changing the parameters via the URL, I assume that you would also need to change the extent values to match the projection. (I can't verify that map.projection is something that you can change via URL). David.
